The invention relates to a method for operating a
temperature control system (100, 500) with at least one component to be temperature controlled (120, 130, 140, 520, 521, 530, 531, 540, 541), at least one
heat exchanger (150, 550, 551) configured to supply and / or extract heat from a
temperature control medium, and at least one first flow control device (110, 510, 511) configured to control a
mass flow rate (dmcool,Des) of the
temperature control medium from the at least one
heat exchanger (150, 550, 551) to the at least one component to be temperature controlled (120, 130, 140, 520, 521, 530, 531, 540, 541) and / or from the at least one component to be temperature controlled. to adjust the temperature-controlling component (120, 130, 140, 520, 521, 530, 531, 540, 541) to at least one
heat exchanger (150, 550, 551), the method comprising: - Determining a target temperature (Tcomp,SP) of at least one component to be tempered (120, 130, 140, 520, 521, 530, 531, 540, 541), - Determining the current temperature (Tcool,in,Act) of the temperature control medium, - Determining a desired
inlet temperature (Tcool,in,Des) of the temperature control medium based on the target temperature (Tcomp,SP), - Determining a control ratio (rReqd) based on the desired input temperature (Tcool,in,Des) and the current temperature (Tcool,in,Act) of the temperature control medium, and - Control of a second flow control device (132, 142, 152, 570, 552) for setting the determined control ratio (rReqd), which in particular leads to a division of the
mass flow.
